Nathan started working out at the age of 21. His goal then was just to get in shape, but over the years a desire to push his fitness to new levels and test himself in new ways has driven his passion to continue.
Nathan practiced bodybuilding, powerlifting, Olympic lifting, running, CrossFit, boxing, kickboxing, jiu-jitsu, Muay Thai, gymnastics, and calisthenics over the years. He now combines these different training principles into a singular methodology for his training.
Nathan has personal experience with being the "hard gainer," having added 80 pounds to his weight, taking him from 135 lbs to 215 lbs at his heaviest. He hovers at 180 now as he feels it is the best weight for him, while also maintaining a body fat percentage equal to or less than ten percent year-round.

Grace is a walking, talking example of a woman who fought being overweight and unhappy, who is now a fit mom that worked out through pregnancy and understands the difficulties that women face.
At the start of her health and fitness journey, Grace had to lose almost 40 pounds to drop weight that had slowly kept on over the years. The weight gain and body issues made her battle insecurity, and she struggled with a desire to get fit and lose that weight. In the end, she got around the mental blocks, put in the work, and built the body she wants.
During pregnancy, Grace was determined to keep in shape. She listened to her body, pushed where she could, pulled back where needed, and managed to keep working out for the full term. This helped her stay in shape for her entire pregnancy and bounce back from pregnancy once she gave birth via c-section.
She was back in the gym after just two weeks and is on the path to her pre-pregnancy weight and fitness. Additionally, she currently runs five days per week and is back to lifting, being able to deadlift, clean and jerk, and complete other lifts with respectable weights. She looks forward to working hard to reach her goals.
Grace practiced bodybuilding, powerlifting, Olympic lifting, running, CrossFit, boxing, kickboxing, and jiu-jitsu over the years. She now combines these different training principles into a singular methodology for her training.
Grace's best athletic performances include but are certainly not limited to:
-
225-pound deadlift
-
125-pound front squat
-
110-pound clean and jerk
-
9-minute mile
-
5 pull-ups
-
60-second headstand
-

-
